/etc/passwd got deleted - but /etc/shadow exists - help

[tachionic]

Hi all

I am a relatively new user of debian
I had been using my woody with 2.2 kernel
In my attempt to make postfix work with TLS
and SASL
/etc/passwd got deleted somehow!!!
But /etc/shadow is present..
I loged in using single user mode and patched little bit so that root
user is reenabled without passwd. Then i changed root passwd
But could someone help me in recreating
my old /etc/passwd from my /etc/shadow

My /etc/shadow

I won't even ask how in the world /etc/passwd got deleted (but I will say I hope you aren't running as root to do day-to-day business).

This is one of the very rare cases where I would say a data backup and reinstallation of Linux may be in order. There are a number of accounts used by the system that I would not feel comfortable guessing about or mucking with, or you may see erratic behavior (and/or open up a vulnerability by setting one up incorrectly).
